Otakenjiro

Worked on the SCFormulaElectric/USC-Electrical-Systems repository, delivering six hardware features over five months focused on schematic and PCB design for accumulator and precharge systems. Applied KiCad and electrical engineering skills to implement versioned schematic organization, develop a reusable accumulator test harness, and redesign voltage indicator and precharge circuits for improved reliability and manufacturability. Enhanced production readiness by integrating a battery management system and refining BOM and PCBA data management. Emphasized maintainability through datasheet-driven component updates, improved grounding, and version control practices. The work established a scalable hardware design foundation, supporting rapid iteration and traceability without reported bug fixes during this period.
